This invention relates to an apparatus for mounting a Waste disposer on a sink drain conduit.

One of the features of this invention is to provide an improved apparatus for mounting a waste disposer on a sink drain conduit wherein fastener means extend through an opening in a chamber portion of the disposer and engage a cooperating opening on a mounting member that is retained on a projecting ledge means on the sink drain conduit.

Another feature of the invention is to provide such an apparatus in which the fastener means comprises a metal wire element shaped to provide spaced projections each constituting a said fastener means.

A further feature of the invention is to provide such an apparatus in which the disposer chamber is provided with a projecting tongue extending partially across a disposer chamber portion opening to retard accidental withdrawal of the fastener means from the opening.

Other features and advantages of the invention will be apparent from the following description of one embodiment thereof taken in conjunction with the accompanying drawings. Of the drawings:

FIGURE 1 is a fragmentary side elevational view partially in section of a portion of a sink, a drain conduit extending downwardly therefrom and a top of a disposer chamber attached to the bottom of the sink drain conduit.

FIGURE 2 is a fragmentary vertical sectional view through a sink drain conduit and the top of a disposer chamber attached thereto by apparatus embodying the invention.

FIGURE 3 is a horizontal sectional view taken substantially along line 3-3 of FIGURE 2.

FIGURE 4 is a fragmentary side elevational view of the top of the disposer chamber showing the wire fastener means in vertical section.

In the embodiment shown in the accompanying drawings there is disclosed a sink provided with a downwardly extending sink flange 11 locked in place in an opening in the sink 10 by means of a top mounting plate 12 hearing upwardly against a gasket 13 on the bottom of the sink 10 and a lower mounting plate 14 hearing downwardly on a wire ring 15 held in an annular groove 16 in the sink flange 11. The two mounting plates 12 and 14 are urged apart to provide a secure locking of the sink flange '11 in place by means of a plurality of spaced mounting bolts 17. As can be seen in FIGURE 1 the mounting bolts 17 press upwardly against the bottom of the top plate 12 and pull downwardly on the lower plate 14 The bottom of the sink flange 11 is provided with projecting ledge means in the form of an annular outwardly extending flange 18 which forms the bottom part of an annular outwardly opening groove 19 at the bottom of the flange 11. Arranged within the groove 19 and thus supported by the flange 18 is a resilient mounting member 20 which is provided with an annular slit intowhich the ledge flange 18 extends. The mounting member 20' is of rubber or similar rubbery material and is provided with inwardly extending flexible fingers 21 which cooperate to extend across the interior of a waste disposer chamber 22. Thus the mounting member 20' has a portion 23 that is located Within the groove 19 functioning as a gasket while the integral fingers 21 operate as splash guards in the customary manner.

The top of the disposer chamber 22 is provided with a circular rim portion 24 that is adapted to be arranged against the outer surface of mounting gasket portion 23 when the disposer chamber 22 is locked in position. The gasket portion 23 has a top part 25 extending above the top of the rim portion 24.

In order to releasably lock the disposer chamber '22 in position there is provided fastener means 26 normally extending through an opening in the disposer chamber portion 24 and into a cooperating opening in the mounting member gasket 23. In the preferred illustrated embodiment this fastener means is in the form of a metal wire having spaced ends 27 and 28 and is provided with a plurality of inwardly formed projections 29.

Each projection 29, when the parts are assembled, extends inwardly through an opening 30 in the circular rim portion 24 of the disposer chamber 22 and engages an inwardly extending openin 31 in the form of an annular groove in the outer surface of the gasket portion 23. As is shown in FIGURE 2 the projections 29 when in position are located above the annular ledge flange 18 so that the disposer chamber 22 is suspended from the ledge flange 18 in a resilient mounting provided by the portion of the gasket 23 between the flange 18 and the projections 29.

As is shown most clearly in FIGURES l and 4 the disposer rim portion 24 contains the disposer openings 30 which are horizontally elongated. In order to prevent accidental withdrawal of the fastener means projections 29 from the opening so and groove 31, the disposer at the rim portion 24 is provided with a projecting tongue 32 at the top of each opening 30 extending downwardly partially thereacross. There is enough space between the bottom of each tongue 32 and the bottom of its opening 30 to permit insertion and withdrawal of the fastener means projections '29. However, when the assembly is locked in position, the tongues 32 prevent accidental withdrawal of the projections 29 particularly when it is noted that the weight of the disposer tends to force the tongues 32 downwardly.

In order to install the disposer of \which the chamber 22 only is shown, it is moved so that the chamber rim portion 24 is received on the outer surface of the gasket portion 23 with the disposer openings 39 aligned with the gasket groove 31. When the parts have been thus assembled, the fastener means wire 26 is grasped by its ends 27 and 28 and sprung outwardly, and then positioned so that the projections '29 engage the openings 30. The ends 27 and 28 are then moved together to press the projections 29 into the openings 30 beneath the tongues 32 and into engagement with the groove 31. The springiness of the fastener means 26 is such that its natural resiliency urges the ends 27 and 29 toward each other and thereby urges the projections 29 into the openings 30 and groove 31. When the disposer is released its weight is resiliently held by the gasket portion 23 and the tongues 32 prevent accidental displacement outwardly of the fastening means projections 29.

The disposer is then secure until it is desired to remove it. In removing, it is only necessary that the disposer be lifted upwardly until the tongues 32 are vertically above the fastener means projections 29. The fastener means 26 then only need by sprung outwardly by forcing apart the ends 27 and 28 to permit disengagement of the projections 29 with the disposer chamber rim portion 24 and the supporting gasket 23.

Having described my invention as related to the embodiment shown in the accompanying drawings, it is my intention that the invention be not limited by any of the details of description, unless otherwise specified, but rather be construed broadly within its spirit and scope as set out in the accompanying claims.
